Abstract

Learning is a process of interaction between students and educators and learning resources in a learning environment that includes teachers and students exchanging information. Learning is also a process to help students learn well. In the context of education, the teacher teaches a lesson so that students can learn and master the content of the lesson to achieve a specified objective, can also influence changes in attitudes, as well as the skills of a learner, but this teaching process gives the impression of only being the work of one party, namely the work of teacher only. The ADDIE and CBL methods are methods used to design a computerized and multimedia-based learning application. In addition to the CBI, CAI, and other learning methods, the ADDIE and CBL methods are also suitable methods for use in learning systems that will make it easier for teachers to convey material. One way of computer-assisted learning is the application of the ADDIE and CBL methods. The ADDIE method is a learning system design model that shows the basic stages of a learning system that are simple and easy to learn. While the CBL method is learning that fully uses a computer. In the process of computer-assisted learning, where the computer is used for the purpose of presenting learning in the form of tutorials, simulations and games. This can really help students to be able to implement a learning while playing system that is very effective for the learning process for students.

Abstract

The beauty of tourist attractions is of course one of the main goals of tourists in Serdang Bedagai in spending their holidays and apart from beauty, there are many other things that attract tourists. The increasing number of tourist attractions and different beauties in Serdang Bedagai, as well as the absence of a system that provides information on priority tourist attractions that are really worth visiting, makes it difficult for tourists to determine the best tourist attraction based on the completeness of the facilities and the beauty of the tourism they will visit. they visit. Based on this problem, a decision support system was designed using a combination of Multi Attribute Utility Theory (MAUT) and Multi-Objective Optimization On The Basis Of Ratio Analysis (MOORA) methods. The results of testing the selection of the best tourist attraction in Serdang Bedagai with the Decision Support System were able to quickly provide decision results for the best tourist attraction in Serdang Bedagai Regency, where with a sample of 5 tourist data it was found that the tourist with the first rank was A4 "Sustainable Bali Beach" with an SPK value of 0.498512.

Abstract

Video files are large in size, especially if they are high quality and have an MP4 extension. The MP4 extension is a minimally compressed format. This poses a problem in the processing of video files and also requires a large amount of storage space. If a video file is large in size, it can affect the file transfer process. Therefore, the file transfer process has two possible outcomes: the video file may take a long time to transfer, or the transfer may fail due to the file size exceeding the maximum storage limit. This issue can be resolved by compressing the video file data. Data compression reduces the storage size of the file on both internal and external memory, thereby accelerating the transfer process as the file size becomes smaller. Data compression has several algorithms that can be used. In this study, the author uses the punctured Elias code algorithm, which is a lossless compression technique, so that the decompressed result of the compressed data is the same as the original data. The design of this system consists of two main processes: the compression process and the decompression process, as well as the process of calculating the performance metrics of the Compression Ratio (RC), Compression Ratio (CR), and Redundancy. In the compression process of a colored video file with the MP4 extension using the Additive Code algorithm, the Ratio of Compression (RC) was 1.52, the Compression Ratio (CR) was 65%, and the Redundancy was 34%. In this video file compression research using the punctured Elias code algorithm, it is hoped that it can help users compress large video files into smaller ones.

Abstract

In a company, hiring the best employees is quite important, as it can affect the level of profit or loss experienced by a company. This has led company management to make every effort to determine the best employees in order to make the right choice. Therefore, the author will create a decision support system that can be used as a reference in hiring the best employees. The method used in this study is the WASPAS (Weight Agregate Sum Product Assessment) method with ROC (Rank Order Centroid) weighting. By applying these two methods, it is hoped that the best possible results will be obtained in determining the best employees to hire. Based on this issue, a Decision Support System (DSS) needs to be developed to support the employee selection process, by applying the WASPAS method with ROC method weighting. The WASPAS method is a method that can reduce errors or optimize estimations for selecting the highest and lowest values. Thus, the main objective of the MCDM approach is to select the best option from a set of alternatives in the face of conflicting criteria. The ROC method is based on the level of importance or priority of the criteria, and the ROC technique assigns weights to each criterion according to the ranking assessed based on the level of priority. In this study, the method applied to generate the best employee acceptance decision is the Weight Aggregated Sum Product Assessment (WASPAS) with ROC method weighting. This method was chosen because it is a decision support model where the main tool is a functional hierarchy with the main input being human perception, in this case, experts in the field or those who understand the issues of selecting the best employees at CV Sihol Pardomuan.

Abstract

A pdf file (Portable Document Format) is a type of document or file format for digital document exchange purposes. Problems with pdf files often occur when we send files with a large capacity so that the process of sending files is wasteful and it will take a long time in the process of sending pdf files. In overcoming this problem, you have to do a compression technique first so that the pdf file saves on sending files. After carrying out the compression process, you will get a smaller file than before. And the goal is to save storage space and also speed up the shipping process.In the compression process, the Prefix Code Algorithm has better compression results than the Unary Code Algorithm, namely the Prefix Code Algorithm obtains a total value of 5.420% while the Unary Code Algorithm obtains a total value of 5.220% in compressing Pdf files. The Prefix Code algorithm obtains greater results compared to the Unary Code algorithm. So the conclusion is that the Prefix Algorithm is better than the Unary Code Algorithm for compressing Pdf files.

Abstract

Queuing problems, the problem faced during the queuing process for taking the queue receipt to get ice cream at Mixue Krakatau is the irregularity in calling the queue serial number which causes a rush when queuing for ice cream which can make the queue atmosphere disorderly and disorganized. . Queuing is a process related to the arrival of consumers to a service facility. If they cannot be served, they have to wait in a queue until they are served and finally leave the facility after being served. One solution to handle the problem of queuing services and ordering queue receipts is to increase the number of machines that handle ice cream and drinks in Mixue Kakatau so that queues run regularly, it should be implemented in a way or approach that is expected to solve the problem of the ordering process and customer views, namely a tiered queuing system where queuing is often used to achieve discipline with the First In First Out (FIFO) method, which is a method for solving queuing problems that can be applied in a way that the customer who first arrives or enters is assumed to be the first to leave. Research results from customer queue simulations using the FIFO (First In First Out) method. It was obtained that the final results of testing the Krakatau Mixue customer ordering queue system gave the smallest value for AWP (Avarage Waiting Process) with an average queue processing time of 10.7 minutes. Implementation using one of the solutions provided by the author gives the final result of the smallest value of AWT (Avarage Waiting Time) with an average service waiting time of 12.9 minutes. AWP (Avarage Waiting Process) average queue processing time is 10.7 minutes. The smallest value of AWT (Avarage Waiting Time) is the average service waiting time of 11.3 minutes.

Abstract

Tama GYM is a place to exercise with a location in the field, which is comfortable and environmentally friendly. The trainer place is quite spacious and is trained by professional instructors at a very affordable entrance price. Fitness instructor is someone who serves as a guide and gives instructions to individuals or groups of people who guide members, to assist members in achieving goals based on physical health, both in physical fitness and body shape appearance by routinely doing fitness. Fitness instructors are usually called sports guides, nowadays many young people and parents are very fond of this sport. In the process of accepting Fitness Instructors, it is still done manually, namely by inputting prospective instructor data in the book so that negligence often occurs among TAMA GYM employees. The owners of TAMA GYM so far have only seen from the appearance of the Fitness Instructor itself, even though in the process of receiving Fitness Instructors must use several criteria. The criteria used in this information are appearance, character, experience, achievement and age. The AHP method is one of the methods used to solve this problem. From the research, the best alternative results fell to A9 on behalf of "simon" with a value of "0.46075".

Abstract

File compression is an important aspect in the development of information technology. The demand for providing information in a short time with a large number and size of files makes compression techniques important. Image files are files that have a lot of characters so they always cause problems with memory storage. There are many algorithms developed for file compression, namely the Huffman Algorithm, Goldbach Codes Algorithm, Elias Delta Codes, Elias Gamma Codes, and Rice Codes. In this research, a comparative analysis will be carried out between the two algorithms for image compression. The analysis carried out will compare the ratio of each algorithm in the image. The analysis results obtained in this research from bitmap files are that the Elias Gamma Codes algorithm has the best compression ratio with a Ratio of Compression (RC) value of 4.17, Compression Ratio (CR) of 28.5%, Redundancy of 71.4%, and Space Saving (Ss) of 72.5% compared to the Rice Codes Algorithm with a Ratio of Compression (RC) value of 2, Compression Ratio (CR) of 54.5%, Redundancy of 46.7%, and Space Saving (Ss ) of 45.5%.

Abstract

Large data sizes result in a waste of storage space required and slow data transfer processes. Compression aims to reduce the size of the data to be as small as possible. Reverse Unary is a type of lossless compression used in this research, which will be measured by Ratio of Compression (RC), Compression and Decompression. The encoding process is only done on image files with jpeg format and encodes using Reserve Unary code, then performs the compression process. From the results of the calculation of the Ration of Compression and Compression Ration of the unary Codes algorithm proves that the reserve unary code is able to reduce data up to 23% in the sense of successful compression, where the data before having a size of 72 MB and after compression the data size is obtained 47 MB.

Abstract

Screenshots or screenshots of monitors such as smartphones, tablets and computer devices. The resulting screenshot image has a small level of smoothness and image sharpness. The level of smoothness and sharpness is said to be one of the main factors in image processing, so zooming is usually done to produce a better image directly but has a poor brightness level. The problem that often arises is that screenshot images have colors that are less bright or dark, making it difficult to understand the contents of the image. This situation will affect the sharpening of the colors in the screenshot image you want to take. Images that have less bright colors can cover up the information contained in the image. For the process of sharpening the color of a screenshot image, a method is needed so that the image can be sent properly.
